Abstract: THERMALLY ACTUATED ROCKET MOTOR SAFETY SYSTEM   ABSTRACT     A thermally actuated rocket motor safety system has a fire temperature pyrotechnic sensor which ignites a gas generator (30) which drives piston (38) to the left.  Firing pin (40) strikes the primer in transfer booster assembly (42).  The transfer booster assembly transmits explosive energy through window (54) in now open block ring (50) to initiate charge (62) which lies adjacent the rocket motor case.  This stresses the rocket motor case by producing a stress raising notch in the case wall.  Subsequent grain burning opens the case to vent the rocket motor pressure.  Inertia mass (70) slides to the right upon acceleration due to normal rocket motor firing and locks in the rightmost position by means of latch (82).  In the locked position, inertia mass (70) prevents leftward motion of the firing pin (40).

Abstract: OPTICAL RECEIVER CIRCUIT         Abstract The circuit is of the type having an input section and a shaping section.  The input section includes a photodiode and a transimpedance amplifier with an AGC shunt device connected between its input nodes.  The shaping section includes, in order, an AGC amplifier, an equalizer amplifier, a buffer amplifier, and a filter.  A controller responsive to the photocurrent controls the impedance value of a  dynamic impedance in the equalizer so that the frequency zero of the equalizer tracks the pole frequency of the input section as it changes in the course of changes in the value of its AGC shunt.  This maintains the frequency response of the shaping section so that it continues to compensate for the frequency response characteristic of the input section.  A trigger responsive to the impedance value of the shunt activates the equalizer only when the shunt is active.          Also disclosed is a particularly advantageous differential configuration for the equalizer which includes a diode bridge and four setting resistors by which the break points for the frequency response can be set.

Abstract: ABSTRACT OF THE DISCLOSURE         Methods and apparatus for selectively controlling the energization of a plurality of lamps in an elevator system,  utilizing a microcomputer based lamp controller, and for detecting failure of the lamps while utilizing a minimum number of communication lines.  A first communica-tion line synchronizes  signals  which  are placed on  the remaining communication lines.  Signals indicating the need for lamp energization are detected by the lamp controller.          When such signals are recognized by the lamp controller, the lamp controller prepares and places signals on a second communication line which requests lamp energization of the associated lamps,  and  it  stores  indications  of  the  re-quests.   Signals  responsive  to  the  detection  of  actual energization of a lamp are placed on a third communication line and directed to the lamp controller.  The lamp con-troller logically relates signals detected on  the  third communication  line  with  the  stored  indications  of  lamp energization requests to determine or test system integri-ty, and to detect lamp burn-out.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for cutting hollow, metal, spirally formed pipes is disclosed.  The apparatus uses two passive, rotatable knife blades to cut the pipe.          An upper knife blade is positioned inside the pipe so that its cutting edge is adjacent to the inner pipe surface.  A lower knife blade is positioned outside of the pipe so that its cutting edge is adjacent to the cutting edge of the upper knife blade in the lateral direction, but is clear of the pipe and upper knife blade in the longitudinal direction.  To cut the pipe the lower knife blade is raised until its cutting edge overlaps the cutting edge of the upper knife blade.          The knife blades then puncture the pipe.  The pipe is rotated through the overlapping blades to completely cut the pipe.  Since the pipe moves spirally (i.e., it moves forward while it rotates), the knife blades are adapted to move in the direction of the pipe during the cutting process.  This permits the overlapping knife blades to cut the pipe rectangularly.  The upper knife blade is attached to a cantilevered boom, and the lower knife blade is attached to a knife holder and a vertical raising device.  These components are all attached to sliding guide rails so that they move with the cutting blades in the direction of the moving pipe during the cutting process.

Abstract: ABSTRACT OF THE DISCLOSURE        The medium and liners of a water resistant containerboard are  each  essentially  completely  impregnated  by  a  liquid  water resistant  agent which  also uniformly coats the  surfaces of the medium and liners with a layer sufficiently thick to cover the outer extremities of fibers protruding from such surfaces.        The coating and impregnation is accomplished by feeding a flat untreated corrugated containerboard in the direction of its open flutes and in a continuous movement into and out of a hot melt bath of the water resistant agent at a controlled speed sufficient to force the liquid agent through the flutes of the containerboard, to as to assure exposure of all surface portions of the board to the hot melt for the same amount of time at the same temperaure conditions.  Upon removal of the board from the hot bath, the board is moved to a position with its leading edge uppermost to drain excess  liquid  agent  from the board,  which  is then moved  to a horizontal position to stabilize the depth of the liquid surface coating by the agent and thence to a vertical position with the leading edge uppermost to reverse the direction of final drainage while the board is cooled to solidify the agent.

Abstract: A DATA PROCESSOR CONTROL UNIT HAVING AN INTERRUPT SERVICE        USING INSTRUCTION PREFETCH REDIRECTION                         Abstract A data processor control unit which provides instructions for execution by a data processor and minimizes instruction cycles lost as overhead is provided.  A pipelined instruction stream is used in which instruction addresses are selectively coupled from a program counter and a prefetch counter to a program memory which provides actual instructions.  The instructions are stored in a prefetch register, decoded and then loaded into an instruction register coupled to the data processor.  When an interrupt service request is made by a device peripheral to the processor, the prefetch instruction address flow is immediately redirected and a predetermined number of interrupt instruction words are prefetched by an interrupt address generator before completion of execution of normal program instructions has occurred.  Therefore, interrupt instructions are fetched and jammed into a pipelined instruction stream regardless of instruction cycle boundaries. Similarly, prefetch instruction address flow is redirected back to normal instruction words before completion of the decoding and execution of interrupt service instructions so that substantially no instruction execution cycles of the data processor are lost as overhead.
